BED-VIBRATOR.

Y SPECIFICATION forming' part of Letters lratent No. 761,862, dated J'une 7, 1904.

Application filed August 28, 1903.

To a/ZZ whom t may concern:

Be it known that we, ALICE A. WALLMAN and ALoIs B. SALIGER, citizens' ofthe United States of America, residing' at New York, in l the county ofNew York and State of New York, have invented certain new and usefulImprovements in Bed-Vibrators, of whichthe following is aspeciiication,such as will enable those skilled in the art to which it appertains tomake and use the same.

The object of this invention is to provide a bed-vibrator which willrapidly agitate the wire mattress of a bed on which a person may belying, thereby producing aslight agitation of said personf whichoperates to start the blood in circulation and overcoming any congestionwhich may have resulted from excessive walking or other exercise or froma cramped position, a further object being to provide such an apparatuswhich is easily and quickly adjusted to a bed of any construction andwhich is positive in operation, economical in construction, and welladapted to accomplish the result desired.

The invention is fully described in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof the invention are designated by suitable reference characters in eachof the views, and in which- Figure l is a perspective view oftheapparatus in operative position, -a portion of a bedframe andwiremattress being shown. Fig. Q is a partial sectional View thereof, takenon the line 2 2 of Fig. l. Q

In the drawings forming part of this speci- [ication we have shown thesidc rod cof a bed of the usual construction, over which is mounted aportion of the usual spring-mat- 'tress c2, all of said bed not beingshown fory the reason that it is of the well-known iron form, but thesame may be of any other construction, as will be understood. Passingaround the side rod a, preferably about the center thereof, is strap ofa frame b2, of iron or other metal, and which is held thereon by meansof bolts or screws b3 in such a manner as not to permit of movement, andthe frame consists of a vertical member b", a horizontal sei-a1110,171,080. (No man.)

member b5 atthe bottom thereof, and a wing member L, provided with anoverhang 67. Mounted on the horizontal member b5 of the -frame b2 is anelectric motor c of the usual or any other construction and to the shaftc2 of which is secured a pinion c3, which engages a gear-wheel 0*,rotatably mounted in the wing member 6G of the frame Z22, and to theouter end of the shaft c5 of which is secured a disk i c, upon which ismounted a pin Ic7 eccentric to the shaft c5. Firmly connected with thewire mattress a2 of the bed is a rod d, the other end of which ispivotally connected with the pin c7, `and upon the front of the verticalmember?)4t of the frame Z22 is mounted a rheostat d2, which is inelectrical communication with the motor c and with a suitable source ofelectric supply, as indicated by the dynamo' d3, said rheostat beingprovided with the usual arm KZ".

When the arm d* of the rheostat d2 is moved froinits normal position, itwill be seen that the motor c isactuated, the speed or power thereofbeing governed by the distance which the arm d" has been moved, land asthe frame 722 is rigidly connected to the side rod c of the bed and therod Z is moved rapidly to and fro by means of the pinion c, gear-wheelc", and eccentric-pin c7, the mattress c2 is also rapidly moved thereby,said movement being of a vibratory nature, and vertical movement ofwhich is prevented by the weight of the bedclothing or of a person lyingthereon, and when it is desired to stop the said movement of the partsall that is necessary is to move the arm di back to its normalposition..

It will be seen from the construction that the apparatus may beconnected with a bed in a few moments or disconnected therefrom andplaced out ofthe way, and the saine may be entirely incloscd in acasing, if desired, thereby preventing the entanglement of thebedclothing or soiling the same with grease or dirt, and various otherchanges in and modiiications of the construction herein shown anddescribed may be made without departing from the spirit of our inventionor sacrificing we claim as ne\v, and desire to secure by Letters Patent,isd

1. In a bed-vibrator, the combination of a bed, a mattress, an electricmotor, and means connected to said electric motor and mattress wherebythe latter is independently vibrated.

2. In a bed-vibrator, the combination of a bed, a Wire mattress, a motorconnected to said bed and Wire mattress whereby an independent vibratorymovement is imparted to said Wire mattress.

3. In a bed-vibrator, the combination of a bed, a motor removablyattached thereto, a

mattress, and means connected to said mattress and motor whereby anindependent vibratory movement is imparted to said mattress.

In testimony that We elaim the foregoingas our invention we have signedour names in presence ofthe subscribing.' witnesses, this 2 i th day ofAugust, 1903.
